Jim Hamilton is vouching for an online Latin course called Latinum. I’m not a big fan of online courses (probably because of my job security as a Latin instructor), but I thought I’d pass this along to see if anyone has tried taking the course, or has some thoughts about the book.

In case the $2 fee above is still too steep, there is yet another Latin Grammar available online for free. On that same textkit.com site, where the free Latin Grammar is provided, there is also a list of textbooks, texts, and resources here.
